Te goal of an athletic stance in skiing is to align the body to have maximum access to the three basic skills, while maintaining a balanced relationship between the CM and BOS. Te basic stance for a skier includes flexion of the ankles, knees, hips, and spine. From a side view, the slant of the lower leg is parallel or nearly parallel to the slant of the upper body. Te overall height of the stance is determined by boot setup, intent, and ability of the skier.
Te importance of this stance cannot be overstated; any style or habit that negatively impacts these elements of an athletic stance will have a negative impact on the skier’s ability to move effectively.
BALANCE AS AN OUTCOME
Balance is also an outcome of effective movement. A skier managing ski-to-snow interaction effectively will maintain equilibrium between the CM and the forces created by the skis.
From an athletic stance, a skier must make constant adjustments to affect the skis and maintain balance. In this dynamic state, even as the skier bends, extends, rotates, and tips, definitive references for effective balance (and body relationships) are identifiable.
Fore/Aft References ■ Te skier’s posture maintains a degree of forward lean relative to speed, terrain, and snow conditions (see photo on the bottom of page 33).
■ Te degree of ankle flex determines the lower-leg angle, which is matched by the angle of the spine (again, see photo on page 33).
Lateral References
Te skier’s hips, shoulders, and hands remain relatively level (perpendicular to gravity) as the CM moves to the inside of the turn.
Rotational References
An imaginary line that crosses the front of the bindings is parallel to lines drawn across the knees, front of the hips, shoulders, and hands.
Tese dynamic-balance references are not the static stance positions described for an athletic stance. Instead, they represent body relationships that result from accurate movements while skiing. A wide variety of movements can be used to turn and tip the skis, and to manage pressure on the skis, but only effective movements will maintain balance and result in the body relationships described previously. For more information on relationships be tween different parts of the body, see page 88.
